Final answer:
Anthropologist Arnold Van Gennep developed the three stages in rites of passage: separation, liminality, and incorporation.
Step-by-step explanation:
In the study of rites of passage, anthropologist Arnold Van Gennep identified three stages: separation, liminality, and incorporation. During the separation stage, individuals are removed from their current social identity and begin preparations for their new stage in life. The liminal period is a time of transition and preparation, where individuals often undergo tests or activities to prepare them for their new social roles. In the incorporation stage, individuals return to the community with a new socially recognized status.
